How do find the median with 4 different numbers?
There would be no median.
Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
Can the median and mean be different?
Yes they can. That is why we have them. We would not need both if they always gave the same value. A mean is the total of numbers divided by the amount of numbers. A median is the middle value in the list when it is in numerical order. Usually they are similar, but not always the same. If there is an extreme number, much different than all the others, then the mean and median will be very different. Take 1, 3, 4, 7, 900. 4 is the Median. 183 is the mean. 183 is not very representative of the set, which is why a median actually works better here.
How do you get the median with an odd amount of numbers?
It is easy to get a median with an odd amount of numbers, as there will always be one number in the middle of the list. So, for example, if you have 7 numbers, n1, n2, n3, n4, n5, n6, n7, the 4th number is always the median, so n4 would be the median value in this case.
What do you do when you have 2 numbers in the middle for median?
If they are the same numbers, it is that number if they are 2 different numbers, the median is the average of those 2 numbers ( the number directly in the middle of the 2 numbers )
Are the mean and median always nearly equal?
No, not always. Sometimes they are equal. Sometimes they are close to each other, but not exactly the same. Sometimes they are very different. It depends on the numbers that are being used to calculate the mean and median. The way each is calculated is different. The mean is got by adding all the numbers and dividing by the amount of numbers. The median is got by arranging the numbers in order and finding the middle value in the list, if there is an odd amount of numbers, or the value half way between the two middle values when there are an even amount of numbers.
What do you do if you can't find the median in a set of numbers?
Every set of numbers has a median, so it can always be got. It is the middle value when they are arranged in numerical order. If there is an odd amount of numbers, then it is in the set, as there is one definite middle number. If there are an even amount of numbers, then you take the two middle numbers and find the value that is half way between them if they are different. You can also add the two numbers and divide by 2, which will also give you the median.
What is the median of these numbers 567891011?
it is always the middle number, in this case 8.
Are median and mean always similar?
No, not always. Median is the number that's in the middle of a group of numerical data. Mean is just the average of a set of numbers, which isn't always in the middle.
How do you find the median when two numbers are in the middle?
If the two numbers are that same in the middle than the median is that number.However if the two numbers are different then you just find the average of those two numbers.
Can a set of data always have a median?
Yes, it can. Even if you have an uneven amount of numbers you can find the median by taking to two middle numbers, adding them together and then dividing by 2.
What if you have no median in a set of numbers?
If you have at least two numbers than you always have a median. If the number of numbers is odd (e.g. you have the number 1, 3, 7, 9, 52), then the median is the middle number when arranged in numerical order (in this example median is 7. If the number of numbers is even (e.g. you have the numbers 1, 3, 7, 9, 52, 103), the the median is the average of the two middle numbers (in this case the average of 7 and 9 which is 8).
